Josie Taylor | October 7, 2021

The Biden administration on Wednesday, October 6,  announced that it would restore climate change protections to the nation’s bedrock environmental law. The proposed changes would require the federal government to evaluate the climate change impacts of major new projects as part of the permitting process. 

Under the Biden administration’s proposed changes, agencies will have to consider the direct and indirect impacts that their projects may have on the climate, specifically how it pollutes American neighborhoods.

The goal of this proposed goal is to protect Americans from the harmful effects of pollution. Air polliution is the biggest environmental risk for early death. World wide, 9 in every 10 people breathe unclean air. 

If an agency’s project was not approved, they could work with local communities to figure out how to make it safer. The federal agenencies and local communities would work together to find a solution that would result in less pollution. 

The Biden administration is expected to publish its proposed rule in the Federal Register on Thursday and will take public comments on its plans for 45 days before issuing a final policy.

Wildfire season sets record for days on high alert

In 2021, the United States Forest Service saw more days on the highest level of wildfire preparedness consecutively than ever before.

Forest Service Chief Randy Moore spoke to the United States House of Representatives subcommittee on Sept. 29 regarding the increasing intensity and of wildfires. Moore said the fires are getting harder to control, according to Iowa Capital Dispatch. Wildfires started in January across the western United States and they continue to burn into October. Millions of acres have burned as fewer firefighters fight the flames, according to Moore.

In June 2021, the Iowa Department of Natural Resources issued air quality alerts due to winds from the West Coast changing the air quality in some Midwestern states. Iowa saw poor air quality on various days throughout the summer because of the wildfires throughout the west. Wildfires are also worsening by scaling mountains and reaching higher elevations than in previous years. According to The New York Times, 50 percent of these fires in 2021 were started by lightning. The other half were traced back to a variety of human-made causes, including power lines and cars.

Moore said these wildfires are milder than in past years based on a couple of metrics, but with fewer firefighters they become tougher to fight. The 2021 season did, however, start earlier than normal.

Joe Biden has a New Goal of Cutting Down Methane Emissions

Josie Taylor | September 27, 2021

The United States and European Union are working on a pledge to cut methane emissions by at least 30% by 2030, President Joe Biden announced on Sept. 17, 2021. He urged countries around the world to join before the U.N. climate summit later this year. 

Cutting out methane would be beneficial for both slowing climate change and for the health of every citizen. There is less methane in the atmosphere than there is carbon dioxide, however it is a much more potent greenhouse gas when it comes to warming the planet. Methane also causes unhealthy air pollution. 

Methane emissions have been going up very quickly recently, and research shows they need to drop by almost half by 2030 to meet the Paris climate agreement goals. This means that the entire world needs to cut methane emissions. 

Methane is a potent greenhouse gas, but it also contributes to surface ozone, which is a toxic air pollutant. Reducing methane improves air quality, while reducing the effects of climate change. Another benefit is that the results are almost immediate. 

Air quality, climate bulletin highlights quality patterns, shifts

The World Meteorological Organization published its first Air Quality and Climate Bulletin on Sept. 3, discussing where air patterns are improving and deteriorating across the globe.

The report discusses the strong connection air quality and climate change have because of the chemical species that impact both. One of the similarities is the affect the combustion of fossil fuels has on air’s breathability and on global warming. A large problem when it comes to air quality is wildfires, according to the bulletin. The report said the fire seasons expose people to “varying levels of pollutants” alongside putting millions of people at high or very high health risks as a result of being downwind from wildfires.

Center for Global and Regional Environmental Research co-director Greg Carmichael assisted in the creation of the organization’s bulletin. He serves on the editorial board for the bulletin and chairs the Environmental Pollution and Atmospheric Chemistry Scientific Steering Committee of the World Meteorological Organization, the group that inspired the report.

Iowa saw poor air quality this summer because of the wildfires in Western states. In late June, the Iowa Department of Natural Resources issued air quality alerts due to winds from the West Coast changing the air quality in some Midwestern states. The alert specifically focused on warning sensitive groups to limit their outdoor exertion within the state. According to the Des Moines Register, these alerts also signaled several towns in the state having “unhealthy” air based on the Air Quality Index. Poor air quality returned later in the summer to Iowa, as residents saw more alerts in August.

The bulletin by the World Meteorological Organization included a section on how COVID-19 and air quality have impacted one another — something that has worried some health officials in Iowa. During various lockdowns of differing degrees, international emissions of air pollutants fell drastically, improving air quality across the world. The report showed nitrogen dioxide emissions dropped nearly 70 percent as a result of COVID-19.

The World Meteorological Organization intends to continue putting out bulletins with more air quality information in the future.

Alissia Milani and Dr. Betsy Stone Discuss Exciting New Research


Nicole Welle | November 30, 2020

University of Iowa undergraduate Alissia Milani recently led a group of researchers in discovering a new compound in the atmosphere that can help track the effects of personal care products (PCPs) on air quality.

Common PCPs, like antiperspirants, shampoos and hairspray, contain colorless and odorless chemicals called cyclic volatile methyl siloxanes. These chemicals can quickly evaporate into the atmosphere after they are applied, and Milani’s group worked on identifying a secondary aerosol tracer called D4TOH in urban environments like Houston and Atlanta to better understand the impact of pollution from PCPs. D4TOH is the oxidation product of D5, one of the most prominent methyl siloxanes found in PCPs, according to the group’s new article.

Graphical Abstract from ScienceDirect article

The health and environmental impacts of PCP use are not yet fully understood, but this work will help provide a new way for researchers to begin tracing and assessing those impacts. Milani hopes that her work will allow researchers across the globe to begin detecting this compound and use it to better understand how PCPs can affect air quality in both urban and rural environments.

This crucial work is only the first step toward better understanding the health and environmental implications of PCP use, but there are steps the public can take in the meantime. Milani says that people should look into the chemicals that make up the products they use and think about what they might be exposing themselves and others to. Some potentially harmful chemicals found in PCPs are not currently regulated, so it is important for people to learn about those chemicals and seek out alternatives that work best for them.

Milani received support from the Iowa Center for Research by Undergraduates and was joined in her work by Dr. Betsy Stone, an associate professor in the Department of Chemistry at the University of Iowa. The article outlining their work was accepted on November 11, 2020.

Saharan Dust Cloud Reaches Iowa and Affects Air Quality

Nicole Welle | July 2, 2020

A giant plume of dust that originated in the Sahara Desert traveled across the Atlantic ocean and into the United States early this week.

The dust cloud first appeared over states in the gulf of Mexico before traveling up into the Midwest. It reached Iowa last weekend, and the EPA issued an air quality forecast for Iowa June 29 placing parts of the state in the “moderate” category. This level of pollution could pose some health risks for a small number of people who are unusually sensitive to air pollution, according to air quality forecasts on AirNow.

The dust plume was part of the Saharan Air Layer, which is a mass of dry, dusty air that forms over the Sahara Desert in the summer and moves over the North Atlantic every few days, according to NOAA. The dust caused the air to appear hazy in parts of the Midwest, especially during sunrise and sunset.

When the wind is strong enough, the dust can reach the United States and be concentrated enough to cause air quality issues. However, the extremely dry air can also help suppress hurricane and tropical storm development over the Atlantic Ocean, and minerals in the dust can help replenish nutrients in rainforest soil when it is able to reach the Amazon River Basin.

EPA Suspends Enforcement of Environmental Compliance Reporting During COVID-19 Pandemic

Nicole Welle | April 16th, 2020

The U.S. Environmental Protection Agency released an order on March 26 announcing the suspension of the enforcement of environmental compliance reporting in response to the COVID-19 pandemic.

Before this change, businesses were required to report and limit all air emissions and water discharges, meet requirement for hazardous waste management and maintain standards for safe drinking water. Businesses that failed to meet these EPA-issued standards could face fines.

The recent order states that factories, power plants, and other facilities are encouraged to keep records of any instances of non-compliance with EPA instituted regulations. However, they will not face any fines for violations as long as the EPA agrees that the COVID-19 pandemic, rather than intentional disregard for the law, is the cause.

In its order, the EPA did not designate an end date for the suspension or address the potential ramifications this decision could have for public health and safety. Allowing industry to police itself could cause air and water pollution to go unchecked and put the safety of drinking water at risk, according to the Iowa Environmental Council.

Compromising access to clean water could make it more difficult for the U.S. healthcare system to provide the sanitary conditions necessary for fighting the COVID-19 pandemic according to the IEC. The Washington Post also reported that the wording of the EPA’s order is broad enough that companies could get away with practices that put public health at risk well into the future.

EPA announces $40 million for diesel emission reductions

Julia Poska | December 27th, 2018

Regional, state, local and tribal agencies currently have the opportunity to clean up their air on the Environmental Protection Agency’s dollar. The EPA announced last week that it plans on awarding approximately $40 million in grants as part of the Diesel Emissions Reduction Act. 

These grants will fund projects that reduce diesel emissions from school buses, commercial vehicles, locomotives and non-road equipment and emissions exposure for local communities. The EPA is especially looking to benefit communities that currently have poor air quality and for projects that will engage locals even once the project has ended.

This program began in 2008 and has awarded funds to the Iowa Department of Transportation in the past. The state matched the 2018 DERA allocation of $275,123 with funds from the Volkswagen settlement to put over $500,000 towards cleaning Iowa’s air.

Interested agencies have until March 6 to apply. Those in EPA region 7, including Iowa, Missouri, Kansas and Nebraska can apply for projects up to $1.5 million.

Analysis of Iowa air quality reveals positive and negative trends

A new analysis of federal air quality data reveals mixed trends in Iowa’s air quality. On one hand, Iowa cut industrial greenhouse gas emissions 11 percent from 2010 to 2014. On the other, Iowa ranks among the top 20 U.S. states for industrial greenhouse gas and toxic air emissions.

Analysts from the Center for Public Integrity studied EPA data from 2010 to 2014.  The Iowa Department of Natural Resources told the Des Moines Register that since 2014 emissions have trended downwards, according to data from their own monitoring stations and facilities.

The Center for Public Integrity found that Iowa’s industrial greenhouse gas emissions dropped  11 percent, from over 60 million metric tons in 2014 to about 54.7 metric tons in 2014. This cut is over five times greater than the 2 percent national average, according to the Register.

Iowa still ranks 19th for industrial emissions, however. Ten Iowa utility or manufacturing companies were among the nation’s top 500 sources of greenhouse gases in 2014.  Four of those were MidAmerican coal plants.  Since 2014, Iowa utilities have made major investments in renewable energy, particularly wind.

Iowa ranks even higher for toxic air emissions: 17th in the U.S.. From 2010 to 2014, toxic air emissions in Iowa actually increased. The Register found that Climax Molybdenum, a chemical plant in Fort Madison, and four others were responsible for half of Iowa’s toxic emissions in 2014. The paper said Climax Molybdenum was the 10th largest emitter of ammonia in the nation that year.

This week’s segment details a study that found a correlation in asthma reduction and a biodiverse environment.

Transcript:

Biodiverse living spaces can have a positive affect on your child’s health

This is the Iowa Environmental Focus.

A new study by the USDA Forest Service found that children who lived in areas with more plant biomass or more biodiversity were less likely to develop asthma. Plant biomass refers to the total percentage of plant life, where plant biodiversity refers to the different types of plant life in an area. The Forest Service collaborated with Massey University in New Zealand to track 50,000 children’s health condition using the country’s comprehensive data base that compiles health information data from most New Zealand citizens.

The study concluded that areas with more plant biomass lessened the risk of developing asthma by six percent while areas with more plant biodiversity reduced the risk of developing asthma by seven percent. In 2015, one in twelve Iowans suffered from asthma. The Forest Service study demonstrates the value of a green environment to our health.
